The yellow mushroom should be improved

Well, the yellow mushroom, for those who don't know, increases by 1 the carrying capacity of the expedition for 4 trips. Sounds good? Well, I think that it should be better xD

The main problem I have is that consuming a yellow mushroom gaves me one additional crate, and that is good, the problem is that also it takes another slot for carrying the mushroom around! So, if I want to gain an additional slot, I have to loss a slot while I am transporting the mushroom. That if I had only one yellow mushroom, because if I have two... I would consume one only to being able to carrying the other one!

See? I don't think it makes much sense. It is like if in a card game a card allows me to draw another card from the deck. It is redundant. Because of that, I would suggest to improve the effects of the yellow mushroom so they improve the carrying capacity of the trek by 2 instead of 1.
